FINGER RING Filed March 17, 1952 ByW Patented June 13, 1933 PATENT OFFICE 1 KARL LQTOELCKE, OF CHICAGO, ILLINOIS FINGER RING Application filed March 17, 1932. Serial No. 599,385.

The invention relates to finger rings, and has for its object the formation of a ring which, when placed on a finger, may be prevented from being displaced therefrom. A

further and incidental object of the'invention is to impart toa finger ring an attractive and unique design or appearance.

The invention will best beunderstood if 1 reference be had to the accompanying draw- 1 {Figure 1 is a perspective View showing the v ring disposedon a finger;

Figure 2 is a view showing a section taken through the knuckle of the finger;

Figure 3 is a view showing a section taken through the finger just behind the knuckle, and l Figure 4 is a sectional view of the finger,

showing the ring turned to a position which 3 will not admit of its removal from the finger.

Referring to the drawing, 1 is the finger and 2 is the knuckle, the ring being designated by the numeral 3.

The knuckle 2 is shown as having a lateral dimension 4 which is substantially great-.

erthanits vertical dimension 5. These variations of dimensions are characteristics of the knuckles of all human beings.

The ring 3 has two internal dimensions which are respectively indicated as 6 and 7, the smaller dimension 7 being less than the larger or lateral dimension 4 of the knuckle 2, and the larger dimension 6 being greater than said lateral dimension 4. Furthermore,

the smaller dimension 7 of the ring 3 is greater than the smaller dimension 5 of the knuckle 2. When, therefore, the ring 3 bears such angular position relatively to the knuckle 2,

that the dimensions 4, 5 and 6, 7 respectively coincide, the ring 3 may be slipped onto or elf the finger 1. If, however, the ring is turned on the finger 1, and the dimension 7 coincides with the dimension 4 of the knuckle, said knuckle will act as a detent to prevent the removal of said ring.

of a knuckle joint, will prevent its removal from a finger.

Having thus described my invention, what I claim is:

A finger ring having plural internal dimensions, one of said dimensions being substantially' parallel to two of the sides and less than the largerdimension of the knuckle of a finger to which the ring is to be applied, andthe other dimension being substantially parallel to the other two sides and greater than the larger dimension of the knuckle, said internal dimensions being substantially at right angles to each other.

In testimony whereof I aflix my signature.

While the general shape of the ring 3 is rectangular, it is evident that it may be of; any geometrical form provided it has a plurality of internal dimensions one of which,
